Description

  The present invention relates to a method for manufacturing a sheet-like product such as a delivery slip, a form, or a label, and particularly relates to a method for manufacturing a sheet-like product including an adhesive.

  Conventionally, when a package is delivered, a delivery slip is used, which is useful for efficient and accurate delivery. For example, one-part delivery slips are often used in which a plurality of types of slips are arranged on one slip sheet, and each slip is simultaneously printed by a printer.

  Such a delivery slip is affixed with a delivery slip and an adhesive layer on the surface opposite to the surface on which the pressure-sensitive adhesive layer of the tack paper is laminated in the order of release paper, pressure-sensitive adhesive layer, and base sheet. A surface sheet is provided that is formed by arranging the slips in a planar shape, and at least the delivery slip has a structure that can be peeled off from the tack paper surface (see Patent Document 1).

  Delivery slips and delivery slips are provided on a single front sheet as described above, so delivery address information, requester information, other barcodes, etc. based on delivery information managed by a computer The management information can be printed at a high speed at a predetermined location on the delivery slip by the printer device. In use, a delivery slip on which predetermined items are printed in advance by a printer is prepared, and the release paper on the back side of the tack paper constituting the delivery slip is peeled off and attached to a predetermined delivery through an adhesive layer.

  Such a delivery slip is supplied as a continuous sheet in which a base sheet having a pressure-sensitive adhesive layer and a surface sheet are overlapped, and a slit is provided between the delivery slip and the sticker slip, and a perforation is provided between the slips. (See Patent Document 1).

  When all the continuous sheets are used as products (delivery slips) and there is no unnecessary part to be discarded, the technique shown in Patent Document 1 can be adopted as it is. In some cases, the size of the continuous sheet does not match the size of the product, resulting in an unnecessary part to be discarded.

  For example, in the production of business form forms, the size of an inch (inch) is generally used due to paper conveyance. However, when a form of A4 horizontal size (vertical 210 mm × width 297 mm) is manufactured, the flow direction is 8.5. It is necessary to cut the bag form to 210 mm. Similarly, in the case of manufacturing a form of A4 vertical size (length 297 mm × width 210 mm), it is necessary to cut a form having a flow direction of 12 mm to 297 mm.

  If you want to make an 8.5 mm form into A4 size, cut the sheet into 8.5 mm and stack it on a pallet. From this state, a method of connecting a cross cutter device and cutting and removing unnecessary portions is common.

Japanese Patent No. 4362198

  However, in the case of a pressure sensitive adhesive sheet (including the above delivery slip) that includes a pressure sensitive adhesive such as tack paper, the adhesive sheet protrudes from the pressure sensitive adhesive sheet at the time of cutting, and the adhesive is applied to the cutting blade. Therefore, there is a problem that the operation must be performed while removing the pressure-sensitive adhesive, which is inefficient. In addition, in the method of cutting the unnecessary part with the cross cutter device, the unnecessary part called the dovetail is dropped for each product, but the cut dovetail adheres to the cutting blade, etc. There is a problem of being mixed in.

  Therefore, the present invention can produce a sheet-like product without separating unnecessary parts into the product or adhering to the machine when separating the product part of each product from the continuous sheet having an adhesive. It aims at providing the manufacturing method of the sheet-like product containing the adhesive which is possible.

In order to solve the above-mentioned problem, the manufacturing method of the sheet-like product including the pressure-sensitive adhesive according to claim 1 is configured by stacking a plurality of sheets via the pressure-sensitive adhesive, and used as a product part. A continuous sheet provided with product parts for a plurality of products, and separating the product parts of each product to produce a sheet-like product, wherein the continuous sheet includes In addition, marginal parts are formed on both sides of each product part along the conveying direction, and the unnecessary parts are set to connect the marginal parts and separate the product parts, and the unnecessary parts are arranged on a circumference. the slitting roller that slitting blades are provided, except a length corresponding to the length of, and a step of cutting the boundary of the product portion and the marginal portion, cuts the boundaries of the product portion and the marginal portion That a pre-process or post-process step, the blade extending in the axial direction by two provided with rollers, characterized by having a step of cutting the boundary between the product part and the unnecessary part.

  According to the method for producing a sheet-like product containing the pressure-sensitive adhesive according to claim 1, from the continuous sheet having the pressure-sensitive adhesive, the boundary between the marginal part and the product part on both sides is cut, and further, using a blade extending in the width direction, Since the boundary between the product part and the waste part is cut, the waste part and the marginal part are discarded together, and the waste part is mixed into the product or attached to the machine. Nothing will happen.

The method for producing a sheet-like product containing the pressure-sensitive adhesive according to claim 2 is the method for producing a sheet-like product containing the pressure-sensitive adhesive according to claim 1 , wherein the sheet-like product is provided with an adhesive layer and a release paper on the back surface. It is a delivery slip in which the base sheet and the top sheet are bonded together with an adhesive. According to the method for manufacturing a sheet-like product according to claim 2 , it is possible to manufacture a delivery slip having a base sheet provided with an adhesive layer without mixing unnecessary portions into the product.

  According to the present invention, when separating the product portion of each product from the continuous sheet having the pressure-sensitive adhesive, the sheet-like product containing the pressure-sensitive adhesive is not mixed into the product or attached to the machine. It can be manufactured.
